The various schemas included in QEMU use a JSON-based format which is, however, strictly speaking not valid JSON. As a consequence, when vim tries to apply syntax highlight rules for JSON (as guessed from the file name), the result is an unreadable mess which mostly consist of red markers pointing out supposed errors in, well, pretty much everything. Using Python syntax highlighting produces much better results, and in fact these files already start with specially-formatted comments that instruct Emacs to process them as if they were Python files. This commit adds the equivalent special comments for vim. Signed-off-by: Andrea Bolognani <abologna@redhat.com> Message-Id: <20200729185024.121766-1-abologna@redhat.com> Reviewed-by: Daniel P.

# @ObjectPropertyInfo:
|
|
#
|
|
# @name: the name of the property
|
|
#
|
|
# @type: the type of the property. This will typically come in one of four
|
|
# forms:
|
|
#
|
|
# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
|
|
# These types are mapped to the appropriate JSON type.
|
|
#
|
|
# 2) A child type in the form 'child<subtype>' where subtype is a qdev
|
|
# device type name. Child properties create the composition tree.
|
|
#
|
|
# 3) A link type in the form 'link<subtype>' where subtype is a qdev
|
|
# device type name. Link properties form the device model graph.
|
|
#
|
|
# @description: if specified, the description of the property.
|

# @default-value: the default value, if any (since 5.0)

# @qom-get:
|
|
#
|
|
# This command will get a property from a object model path and return the
|
|
# value.
|
|
#
|
|
# @path: The path within the object model. There are two forms of supported
|
|
# paths--absolute and partial paths.
|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|
|
# or link<> properties. Since they can follow link<> properties, they
|
|
# can be arbitrarily long. Absolute paths look like absolute filenames
|
|
# and are prefixed with a leading slash.
|
|
#
|
|
# Partial paths look like relative filenames. They do not begin
|
|
# with a prefix. The matching rules for partial paths are subtle but
|
|
# designed to make specifying objects easy. At each level of the
|
|
# composition tree, the partial path is matched as an absolute path.
|
|
# The first match is not returned. At least two matches are searched
|
|
# for. A successful result is only returned if only one match is
|
|
# found. If more than one match is found, a flag is return to
|
|
# indicate that the match was ambiguous.
|
|
#
|
|
# @property: The property name to read
|
|
#
|
|
# Returns: The property value. The type depends on the property
|
|
# type. child<> and link<> properties are returned as #str
|
|
# pathnames. All integer property types (u8, u16, etc) are
|
|
# returned as #int.
|
|
#
|
|
# Since: 1.2
